This study followed a pilot from the same center on patients treated in 2007.A retrospective cohort study.A quaternary care center in Vancouver, B.C., Canada.Patients undergoing cardiopulmonary bypass grafts (CABG), conventional valve replacements, combined CABG-valve replacements, transfemoral TAVI, or transapical TAVI in 2008.Data from 679 charts on demographics, medical history, medications, laboratory results, surgical procedure, and anesthesia were abstracted and analyzed using univariate and multivariate analyses.
